HEATING AND CRUSHING ROLLS FOR OIL-PRESSES.

SPECIFICATION forming part of Letters Patent No. 418,116, dated December24, 1889.

Application filed February 26, 1889. Serial No. 301,277. (No model.)

To @ZZ whom it 71mg/ concern/.-

Be it known that I. VILLIAM R. FEE, of Cincinnati, county of Hamiltonand State of Ohio, have invented certain new and useful Improvements inHeating and Crushing Rolls for Oil-Presses; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which like letters andfigures refer to like parts.

My invention relates to the construction of machines for simultaneouslyheating and crushing seeds of various kindsJ especially cotton-seed, asa preliminary operation to pressing them for obtaining oil, and will beunderstood from the following description.

In the drawings, Figure 1 is a front view of my device, a part of thecasing and shelves being broken away, showing the interior arrangementof the rolls. Fig. 2 is a view of the exhaust end of the machine. Fig. 3is a vertical section on the line x 0c, Fig. l. Fig. 4: is an end Viewon the line y y, Fig. l, showing how the boxing is mounted in the slotof the frame. Fig. 5 isa longitudinal sectional view of a convenientform of the joint j, drawn on an enlarged scale.

In detail, f is the frame-work, each side composed of an upright havinga cent-ral vertical slot, as indicated in Fig. 4. In this slot are setthe boxings bm, in which are journaled the axles of thecylindrical rollso", preferably set one above the other, in the manner indicated in Fig.3, the upper roll being' set atan angle for convenience in dropping theseed directly between it and the roll next In the sides of the case arefixed the inclined shelves s and horizontal shelves s.

h is the hopper, having a sliding gate g in its side to regulate theamount of material that is delivered to the feed-wheel f', the latterbeing mounted on an axle having bearings in the sides of the case, oneend carrying a pinion which engages with a similar pinion on the axle ofthe roll below it. The gate g can be moved up or down at the pleasure ofthe operator, cutting off or en'- larging the space between the side ofthe hopper and the teeth of the feed-wheel. The material as thus fedthrough the hopper falls upon the feed-wheel, is carried down by itster.

revolution and thrown between the iirst set of rolls, and after passingthese it falls upon the inclined shelf on the one side and thehorizontal shelf on the other and is carried between the next pair ofrolls, and so on until it is finally delivered by the lowest inclinedshelf into a receptacle beneath the frame-work. These rolls, as has beensaid, are mounted on stub-axles a, which are journaled in bearingsconnected to the framework, and are hollow, and connected with thesestub-axles a are rotary joints j, a con.

vexhaust-pipe e0@ through Ts t.

p is a pulley mounted on one of the axles of the lower roll, and b isthe belt for driving the mechanism. Y

The rolls r are hollow, and at each end is a bent Siphon-pipe S2, asshown in Fig. 3, connected to the inner end of the hollow axle of therolls, its other end extending downward, for taking up and carrying' offany water that may accumulate in the rolls from condensation. Steambeing admitted to the inlet-pipe z' passes up through theconnecting-pipes 1 into the interior of the hollow cylindrical rolls frand heats them, and its circulation through the rolls carries olf anywater through the siphonpipes. The steam is exhausted at the oppositeends of the rolls through these hollow stub-axles a into and out of theexhaustpipe em. An additional pinion is mounted on the axle of the upperroll, which engages with a similar pinion mounted on the axle of thefeed-wheel for driving the lat- W'hen the rolls are heated to asufficient degree, power is applied, the rolls revolve, the cotton orother seed is delivered to the hopper, passes downward through theseries of rolls, andis heated, so that the oil-cells are repeatedlyexpanded and crushed between IOO the heated rolls, until, after a seriesof reductions and continued beatings and expansions of`the meal, it ispassed down below into the receptacle beneath the frame.

The boxings in which are journaled the axles of the rolls are set intothe long' slot of the frame, as shown in Fig. 4, and the rolls, restingone upon another, are thus allowed a vertical up and down movement; buton account ot the length of the pipes that connect the axles with theinlet and exhaust steampipes this vertical movement will not be so greatas to loosen any of the joints of the pipes. It' it should becomenecessary in any case, lexible couplings may be used between the Ts ofthe inlet and exhaust pipes or between the rotatable joints j and the Tsof the steam and exhaust pipes; but after several trials it is foundthat this vertical movement of the rolls up and down in the slot ot' theframe is not so great as to aitect the tightness of ythe joints whenmetal connections are used.

Iam aware that rolls have been used for crushing seeds and othermaterial, and I am aware that devices have been used :tor heating theproduct; but Ik am not aware that any machine has "heretofore beenconstructed, known, or used wherein the operationV of crushing andheating seed is performed sini ultaneously by hollow rolls having'interior vchambers to which steam and heated vapor are supplied in themanner herein described. What I claim as my invention, and desire tosecure by Letters Patent, is the following:

l. A machine for crushing oil-bearing seeds, comprising a series ofhollow rolls set one above the Vother in an inclosing-case, and a seriesof shelves connected tothe frame-work and` located between each adjacentpair of rolls for carrying down the product, these rolls being journaledin boxes loosely set in the frame'fwork, the boxings being provided withrotatable joints and connections with steam inlet and exhaust pipes,substantially as shown and described. v

' 2; A mechanism for crushing oil-bearing seeds, comprising aninclosing-case, a series of hollow rolls mounted therein one aboveanother, rotatable j oints connected to the boxings of such journals, asteam-inlet pipe connected to such rotatable joint on one side and anexhaust-pipe connected to a similar joint on the other side, andinclined and horizontal shelves connected to the inside ot' such casefor carrying downward the product successively between adjacent rolls,the interior of such rolls forming a steam-chamber and provided withsiphon-pipes at one or both ends of it for carrying off the condensedsteam, with means for driving the roll mechanism, substantially as shownand described.

3. A mechanism for crushing oilbearing seeds, comprising an outer casehavin g a hopper at its upper end, a feed-wheel below such hopper, aseries of hollow cylindrical rolls journaled in the sides'of such caseone above another, their boxings connected with rotary joints, which arein turn connected on one side to a steam-inlet pipe and on the other toan exhaust-pipe, a series of shelves connected to the inner sides of thecase for carryingthe crushed meal successively between the adjacentpairs of rolls',and a series of geared pinions mounted upon the axles oftherolls forsteadying and maintaining` their motion,with means forheating and revolving` the rolls, alll combined substantially as shownand described.

4,. In a seed-crus hing,` machine, a series of rolls having' interiorheating-chambers carried on hollow axles connected therewith and mountedone above another in aframe-work, a series of shelves connected theretoand located between each pair of rolls for feeding the material thereto,and inlet and exhaust pipes for conveying and discharging vtheheatingbody to and from such chambers through such axles and connectedto the latter by rotatable joints, with means for revolving themechanism, all combined substantially as shown and described.

In witness whereof I have hereunto set my hand this 19th day ofFebruary, 1889.
